AN URGENCY ORDINANCE OF THE TOWN OF LOS ALTOS HILLS
AMENDING TITLE 10 (ZONING AND SITE DEVELOPMENT) OF THE
LOS ALTOS HILLS MUNICIPAL CODE TO ADD ARTICLE 15 TO
CHAPTER 1 ESTABLISHING REGULATIONS FOR THE SUBDIVISION
AND DEVELOPMENT OF QUALIFIED SENATE BILL 9 PROPERTIES
WHEREAS, this Ordinance is adopted as an urgency ordinance pursuant to Government Code
Section 65858. The facts constituting the urgency are as follows:
a) A severe housing crisis exists in the state with the demand for housing outstripping supply.
b) In September 2021, Governor Newsom signed into law Senate Bill 9 ("SB 9"), entitled the
"California Home Act". Among other provisions, this bill adds Sections 65852.21and
66411.7 to the Government Code and becomes effective on January 1, 2022.
c) SB 9 requires cities and counties, including the Town of Los Altos Hills ("Town"), to
ministerially approve a parcel map for an urban lot split and/or a proposed housing
development containing a maximum of two residential units within a single-family
residential zone, if the two -unit or subdivision project meets certain statutory criteria. SB
9 specifies that proposed projects and subdivisions cannot be proposed in prohibited
locations under Government Code Section 65913.4(a)(6)(B)-(K), such as in an earthquake
fault zone, lands under conservation easement, a federally designated flood plain, and high
fire hazard severity zones as defined under state law.
d) SB 9 further restricts the standards and regulations that local agencies, including the Town,
may impose on qualifying two -unit or subdivision projects. For example, SB 9 specifies
that local agencies may impose only objective zoning, subdivision, and design standards
that do not conflict with the statutes, but such standards must not physically preclude a unit
size of 800 square feet. In addition, SB 9 permits a local agency to deny a proposed two -
unit or subdivision project only if the agency's Building Official makes a written finding
based on preponderance of the evidence that the proposed project would have a specific,
adverse impact upon public health and safety or the physical environment, which is a very
high standard for municipalities to meet under the statute.
e) The Town's natural beauty including the hills and views of the Bay, and significant
residential communities is a uniquely valuable public resource. A significant number of
parcels within the Town are also within high fire hazard severity zones, earthquake fault
zones and/or covered by conservation/open space easements. The Town has substantial
interests in protecting the community against these hazards and restrictions in promoting
development projects. The reasonably regulated and orderly development of single-family
residential construction and subdivision projects as permitted by SB 9 is desirable, and
unregulated or disorderly development represents an ever-increasing and true threat to the
health, welfare and safety of the community.
Ordinance 598 Page
f) The default standards contained in the new state law include no objective zoning,
subdivision, and design standards, including those contained in the Town's Zoning
Ordinance such as, for example, floor area, height, fencing regulations, subdivision and
site development standards and regulations that require development projects including
accessory dwelling units be designed to respect the visual and acoustic privacy of primary
residences on contiguous lots and to preserve the scenic views of principle structures on
contiguous lots.
g) The Town has received multiple public inquiries from architects, developers, and residents
regarding SB 9 development projects and the new state law, underscoring the need for the
Town to update its regulatory scheme to bring it into compliance with the requirements of
the bill.
h) SB 9 specifically authorizes local agencies to impose objective zoning, subdivision, and
design standards consistent with the bill's provisions, and to adopt an ordinance to
-- - implement its provisions. SB 9 further provides that such ordinances are not considered a
"project" under the California Environmental Quality Act (CEQA).
i) On November 18, 2021, the City Council considered the following amendment to the
Zoning Ordinance for the purpose of amending its local regulatory scheme pertaining to
single-family home developments and subdivisions in a manner that complies with the new
state law and is consistent with California Government Code Sections 65852.21and
66411.7, as amended.
j) California Government Code Section 65858 authorizes the Town to adopt an interim
urgency measure by a four-fifths (4/5ths) vote where necessary to protect the public health,
safety, and welfare without following the procedures otherwise required prior to adoption
of a zoning ordinance.
k) Any interim urgency measure adopted pursuant to Government Code Section 65858 shall
be of no further force and effect forty-five (45) days from its date of adoption unless
extended by the legislative body. During the effective term of the urgency ordinance, Town
staff intends to undertake further study and present its recommendations to the City Council
regarding permanent revisions to the Town's regulatory scheme pertaining to residential
development and subdivision projects and consistent with the goals and policies of the
Town's General Plan, California Planning and Zoning Law, and the provisions of
California Government Code Section 65858.
WHEREAS, the City Council finds and determines that the immediate preservation of the public
health, safety and welfare requires that this Ordinance be enacted as an urgency ordinance pursuant
to Government Code Section 65858, and take effect immediately upon adoption. Therefore, this
Ordinance is necessary for the immediate preservation of the public peace, health, safety and
welfare and its urgency is hereby declared.
WHEREAS, pursuant to Section 15001 of the California Environmental Quality Act (CEQA)
Guidelines, this ordinance is exempt from CEQA based on the following:
Ordinance 598 Page 2
(1) This Ordinance is not a project within the meaning of Section 15378 of the
State CEQA Guidelines, because it has no potential for resulting in physical
change in the environment, directly or ultimately.
(2) This Ordinance is categorically exempt from CEQA under Section 15308 of
the CEQA Guidelines as a regulatory action taken by the Town pursuant to its
police power and in accordance with Government Code Section 65858 to assure
maintenance and protection of the environment pending the evaluation and
adoption of contemplated local legislation, regulation and policies.
(3) This Ordinance is not subject to CEQA under the general rule in CEQA
Guidelines Section 15061(b)(3) that CEQA applies only to projects which have
the potential for causing a significant effect on the environment. For the reasons
set forth in subparagraphs (1) and (2), above, it can be seen with certainty that
there is no possibility that this ordinance will have a significant effect on the
environment.
NOW, THEREFORE, the City Council of the Town of Los Altos Hills does hereby ordain as
follows:
SECTION I. FINDINGS.
Based on the entirety of the record as described above, the City Council for the Town of
Los Altos Hills hereby makes the following findings:
1. All of the facts and recitals above are true, correct, incorporated herein and made a
part hereof such that there exists a current and immediate threat to the public health, safety, and
welfare requiring immediate implementation of an urgency ordinance to regulate residential
development projects, subdivisions and site developments in the Town of Los Altos Hills.
2. The urgency ordinance is necessary for the immediate preservation of the public
peace, health, and safety because the subdivision of lots and design and construction of single-
family residences, duplexes and accessory dwelling units pursuant to Senate Bill 9 (SB 9) without
adequate standards can cause: land use and site development conflicts and incompatibilities
including public safety, visual, privacy, acoustic and aesthetic impacts which would negatively
impact the public welfare and the unique quality and character of the Town.
3. Based on the recent amendments to state law with respect to the regulation of SB 9
units and lot subdivisions, there is a need for the Town to update its current codes.
4. Pursuant to Section 15001 of the California Environmental Quality Act (CEQA)
Guidelines, this ordinance is exempt from CEQA based on the following:
(a) This Ordinance is not a project within the meaning of Section 15378 of the State
CEQA Guidelines, because it has no potential for resulting in physical change in
the environment, directly or ultimately.
Ordinance 598 Page 3
(b) This Ordinance is categorically exempt from CEQA under Section 15308 of the
CEQA Guidelines as a regulatory action taken by the Town pursuant to its police
power and in accordance with Government Code Section 65858 to assure
maintenance and protection of the environment pending the evaluation and
adoption of contemplated local legislation, regulation and policies.
(c) This Ordinance is not subject to CEQA under the general rule in CEQA Guidelines
Section 15061(b)(3) that CEQA applies only to projects which have the potential
for causing a significant effect on the environment. For the reasons set forth in
